WINDOW-OPERATING DEVICE.

To all wizom it may concern:

Be it known that I, NILS H. ANDEnsoN, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in lVindow- Operating Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to window operating devices, and has for its object such a construction and arrangement of the operative elements that it will best effect an easy movement free from all tendency to bind or cramp. My invention further consists in efficient means for securely locking the closed window or windows to the sill Referring to the drawings:

Fig. 2 is an enlarged upper plan view of the operating levers in a closed position, broken view of the actuating rod and broken sectional view of one of the win- (lows;

Fig. 9 is an enlarged view of a bracket carried by the actuating rod on line 99 of Fig. 6; and

Fig. 10 is an enlarged broken detail view of one of the operating levers.

As before mentioned, the principal object of my invention is to so construct and arrange the different elements adapted to operate a series of windows with as little friction and consequent loss of power as possible, and to effect this result, it is necessary that the centers of all the moving parts to operate the windows be in line with the center of the actuating rod, and in the same horizontal plane therewith when the windows are closed. The line of strain or applied power to operate the windows must necessarily pass through the center of the actuating rod and the center of the operative elements connected therewith in order to avoid any tendency to cramp or bind.

The windows 12 and 3 represent part of a line of windows adapted to swing on their pivots 4 through the medium of the longitudinally actuating rod 5 and the levers 6 and 7 Brackets, similar to 8, having antifriction rolls 9, are attached to the Window sill 1 0 and support the rod 5 at intervals throughout the entire system. As the operative mechanism for each window is the same, and as only one operative mechanism is shown, a brief description of the same will sufiice.

The frame 11 carrying the antifriction rolls, is secured to the bracket 8 by screws 12, andl3 is a bracket secured to said frame which supports the sliding bolt 14 pivotally connected to the inner end of the short lever 6. This leveris forked and embraces the central portion of the long lever 7 and is pivotally connected therewith by pin 15.

The outer end of lever 7 is pivotally supported to the sliding bolt 16 mounted in the bracket 17 secured to the angle iron 18, Fig. 4E, secured to the lower rail 19 of the window. The inner end of the long lever 7 is pivotally connected to the rod 20 rota-- fit) tably mounted in the bracket 21 adjust-ably secured to the actuating rod by U clamp It is important in order to secure a free and easy movement of the operative levers that the pivotal connection of each end of the lever 7 and the inner end of the lever 6 should be in some form of a. universal joint. These levers may be equipped with the universal joint shown in Figs. 7 and 8. 23 is a block adapted to have a horizontal movement on the pins 24, 24, 2 1", in the forked ends 25, 26, and 2'? of the members 1 1;, 16 and 20see also Figs. 2 and 3. The ends of the levers engaging these forked ends are each provided with the opening 23, Figs. 5 and 8, adapted to embrace the block with the lip 29 engaging with the groove 30 of the block as a fulcrum point in the vertical tilting movement of the levers.

The means provided for locking the window or windows in closed position consist of the angular plate 31, located near the outer end of the lever 7, and the pin 32 located on the sill 10. This plate is adapted to be adjusted, with respect to the position of the pin and is then secured to the lever by the screws 33. In other words, the adjustable feature of the plate overcomes the ditliculty of locating the exact position of the hole for the pin were the plate immovably secured to the lever; as it is, the pin can be approximately located, and the plate adjusted to it.

To increase the bearing surface of the fiat base of the bracket 21 on the rod 5, parts 3st of the stock are broken down to conform to the circular construction of the rod as shown in Figs. 6 and 9.

When the windows are closed, the position of each set of levers opposite each window is in the position shown in Fig. 2. The movement of the actuating rod 5 in the direction of arrow (0 will cause the levers to move bodily in the same direction until the collar 35 and the shoulder of the forked end 26 impinge against their respective brackets 13 and 17. T his idle movement of the levers is solely for the purpose of re leasing the locking plate from its engagement with the pin 32. The instant this is done, the outward movement of the windows will begin by means of the pressure exerted against the beforementioned brackets, and this pressure will continue to the full window opening as shown in Fig. 6. All tendency to bind or cramp in any of the moving parts is overcome by means of the novel arrangement and construction of the several operative elements, viz; the several centers of movement of these operative elements being in the same horizontal plane with the central line of the actuating rod when the windows are closed, will. not only facilitate an easy and frictionless starting movement to be maintained during the outward travel of the windows by reason of the fact that the centers of motion of the several operative members will substantially remain in line with the central line of the actuating rod during such outward movement. T he centers 2 1, 24 of the levers are always in line with each other, as represented by line A, Fig. 6, and this line is always at right angles to the center line B, ofthe rod 5 inany and all positions occupied by the levers. The above arrangement and the result obtained thereby could only be effected by locating the inner pivotal connections of the levers on a line with the central line of the actuating rod and between the rod and windows rather than on top or below the rod as uniformly arranged in devices of this character.

Actuating the rod in a direction .oppo site to that required for opening the same will'ef'fect a closing movement greatly assisted by gravity, which will lose it force when the windows have nearly assumed a vertical position, with the operating levers in the position shown in Fig. 3, when a fur-= ther closing movement of the actuating rod will draw out the bolts 1e and 16 and cause the angularly arranged plate 31 to engage the sill-pin 32, Fig. 2, and bring the windows firmly against the sill. When the windows are thus locked, the collar 36, on the bolt 14, will engage the bracket 13 and pre vent excessive strain being brought against the sill-pin.

Having thus described my invention, what I claim is 1. A window operating device comprising an actuating rod, a long and short lever between the rod and window, one end of the long lever pivotally supported to a fixed member carried bythe rod, the other end of said lever pivotally supported to a member movable parallel with the rod and mounted in a support carried by the window, the short lever pivotally supported by one end to the long lever and its opposite end to a member carried by a fixed support and also movable parallel with the rod.
